Abstract

An interfold tissue product comprises a tissue stack formed by stacking multiple tissue sheets, wherein each of the tissue sheets is folded in half at least twice, two opposite edges of each tissue sheet created after the first folding are not aligned and form staggered opposite edges, and according to a stacking order of the tissues, the staggered opposite edges (1′, 1″) of one tissue (1) in each pair of two adjacent tissues and the staggered opposite edges (2′, 2″) of the other tissue (2) in each pair of adjacent tissues are respectively located at two opposite sides of the tissue stack. Although the thickness of the staggered portions at the opposite edges of each tissue sheet is thinner than that of the remaining portions thereof, such difference in thickness does not accumulate when the tissue sheets are stacked, and the entire tissue stack still has a a uniform thickness, so as to ensure the tissue stack will not tilt to one side, and to guarantee a neat arrangement of the tissues, such that placement of the tissue stack is stable.

Description

TECHNICAL FIELD

The present disclosure relates to tissue products, and particularly to a folded tissue product that is a stack of tissues stacked by a plurality of folded tissues.

BACKGROUND

In the folded tissue product, a plurality of tissues is stacked to form a stack of tissues, and each tissue is folded twice, and then each tissue and the adjacent upper and lower tissues are inserted into each other. In a folded tissue product available in the market, each tissue is folded at least twice. After a first folding, the two opposite sides of each tissue are not aligned with each other, thereby forming staggered opposite sides, and the staggered opposite sides of all tissues are located on the same side of the stack of tissues. In each folded tissue, the thickness of a part where the opposite sides thereof are staggered with each other is thinner than other parts. After multiple tissues are superimposed, the thickness of the entire stack of tissues will be obviously uneven, and the thickness of the side of the tissue where the opposite sides are staggered with each other is significantly thinner than the thickness of the other side opposite to the side, which causes the entire stack of tissues to be skewed and affects the neatness of the arrangement of the tissues, and even makes it difficult to place the entire stack of tissues stably.

SUMMARY

The present disclosure aims to provide a folded tissue product to overcome the defect that the entire stack of tissues is skewed due to uneven thickness.
The present disclosure is implemented as follows. A folded tissue product includes a stack of tissues stacked by a plurality of tissues. Each tissue is folded at least twice. After a first folding, two opposite sides of each tissue are not aligned with each other to form staggered opposite sides. According to a stacking order of the tissues, in each two adjacent tissues, the staggered opposite sides of one of the tissues and the staggered opposite sides of the other tissue are respectively located on two opposite sides of the stack of tissues.
As a best embodiment, in the first folding of each tissue, a ratio of a width of a narrow part on one side of a fold line to a width of a wide part on the other side of the fold line is in a range from 1/2 to 3/4.
The present disclosure has the following advantages. Since the staggered opposite sides of each two adjacent tissues are respectively located on two sides of the stack of tissues, although a thickness of the part of each tissue where the opposite sides thereof are staggered with each other is thinner than the thickness of the other parts of the tissue, such a difference in thickness will not accumulate due to the stacking of the tissues, and thus the thickness of the entire stack of tissues is still uniform. Therefore, the entire stack of tissues will not be skewed, ensuring the neatness of the arrangement of the tissues, and enabling the entire stack of tissues to be placed stably.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For the convenience of understanding the present disclosure, the present disclosure is described more fully hereinafter with reference to the accompanying drawings. Preferable embodiments of the present disclosure are presented in the accompanying drawings. However, the present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the disclosure of the present disclosure more thorough and comprehensive.
A folded tissue product of the present disclosure includes a stack of tissues stacked by a plurality of tissues. As shown in FIG. 1, each tissue is folded twice. In a first folding, a dot dash line A-A is used as a fold line, and in a second folding, a dot dash line B-B is used as a fold line. The two fold lines are perpendicular to each other. The first folding is an asymmetrical folding. The two opposite sides 1′ and 1″ are not aligned with each other to form staggered opposite sides. As a possible embodiment, each tissue can also be folded more times, such as three times, four times, or the like. The fold line of each folding is perpendicular to the fold line of the previous folding. In addition to the first folding that is the asymmetrical folding, the other foldings are all symmetrical foldings.
FIG. 2 shows a stacking structure of a stack of tissues stacked by the folded tissues shown in FIG. 1 by taking three tissues as an example. As shown in FIG. 2, the staggered opposite sides 1′ and 1″ of the tissue 1 are located on a left side of the stack of tissues, the staggered opposite sides 2′ and 2″ of the tissue 2 are located on a right side of the stack of tissues, and the staggered opposite sides 3′ and 3″ of the tissue 3 are located on the left side of the stack of tissues, and so on. According to the stacking order of the tissues, in each two adjacent tissues, the staggered opposite sides of one of the tissues and the staggered opposite sides of the other tissue are respectively located on two opposite sides of the stack of tissues. Therefore, although a thickness of the part of each tissue where the opposite sides thereof are staggered with each other is thinner than the thickness of the other parts of the tissue, such a difference in thickness will not accumulate due to the stacking of the tissues, and thus the thickness of the entire stack of tissues is still uniform. Thus, the entire stack of tissues will not be skewed, ensuring the neatness of the arrangement of the tissues, and enabling the entire stack of tissues to be placed stably.
In the embodiment shown in FIG. 2, two adjacent tissues are inserted into each other. As a possible embodiment, two adjacent tissues may not be inserted into each other, and the upper tissue is simply placed on top of the lower tissue.
As a best embodiment, as shown in FIG. 3, in the first folding of each tissue, the width of the narrow part on one side of the fold line A-A is W1, the width of the wide part on the other side of the fold line A-A is W2. The ratio of W1 to W2, namely W1/W2, is preferably in a range from 1/2 to 3/4.
The above-mentioned examples are merely illustrative of several embodiments of the present disclosure, which are described specifically and in detail, but it cannot be understood to limit the scope of the present disclosure. A plurality of variations and modifications may be made by those skilled in the art without departing from the scope of the present disclosure, which are all within the scope of protection of the present disclosure. The protection scope of the present disclosure shall be defined by the appended claims.

2. The folded tissue product of claim 1, wherein in the first folding of each tissue, a ratio of a width of a narrow part on one side of a fold line to a width of a wide part on the other side of the fold line is in a range from 1/2 to 3/4.
